Wires are a very important part of circuit transformation. At present, household wires on the market are mainly divided into copper wire and aluminum wire. Next, I will give you an analysis of the household electric wire is the choice of copper wire or aluminum wire is better?
1.Load power: copper wire and aluminum wire with the same cross-sectional area. The load power of the copper wire is greater than that of the aluminum wire. For example: Both are 2.5 square lines, if the aluminum wire can load 2500 watts, then the copper wire can load 3000 watts.
2.Flexibility: copper wire is more flexible, easy to bend, strong fatigue resistance. Aluminum wires are relatively easy to break when bent.
3.Stability: Aluminum wire is very easy to oxidize, which makes the resistance larger, reduces the wire load, and is prone to safety problems. However, the stability of the copper core is excellent.
4.Resistivity: The copper wire resistivity is small, which is lower than 1.68 times than the resistivity of the aluminum wire, which causes the power loss of the aluminum wire to be relatively large, and the heat is relatively serious, which affects the utilization rate of electricity.
5.Price: The price of aluminum wire is much cheaper than that of copper wire. The price of copper wire is generally many times that of aluminum wire, and copper wire is heavier than aluminum wire.
Jiapu wire and cable recommendations: When choosing a household wire, be sure to use copper wire, avoid using aluminum wire. The aluminum wire has poor electrical conductivity, and the wire is prone to heat when used, which may cause loose joints or even fire. In addition, in construction, we should pay attention to not directly excavating trench electric wire on the wall, but to adopt regular casing installation to avoid leakage of electricity and fire.
